RFA Module

The RFA module performs the initial search for a programmed key. The RFA module sends a message over the MS-CAN to the BCM indicating whether or not a programmed key is detected. If no programmed key is detected, the BCM activates the PATS transceiver in an attempt to detect a programmed key in the back location. For additional PATS information, Refer to: Passive Anti-Theft System (PATS) - System Operation And Component Description .

The RFA module does not require PMI when replaced.
